摘要： A surface emitting semiconductor laser that is easy to manufacture and has a high-intensity fundamental lateral mode optical output power. The surface emitting semiconductor laser has a semiconductor substrate on which are sequentially laminated a lower n-type DBR layer, an active layer region, an upper p-type DBR layer, a p-side electrode that is an upper layer of the upper n-type DBR layer and functions as an upper electrode provided with an aperture that forms an emission region for a laser beam, and a current confinement portion formed by oxidization. On the basis of the reflectance of a cavity in a region corresponding to the p-side electrode, a metal aperture diameter (Wmetal) of the aperture and a diameter (Woxide) of the current confinement portion are determined such that the difference between an optical loss of a cavity in a higher-order lateral mode of a laser beam and an optical loss of a cavity in a fundamental lateral mode of a laser beam becomes larger.
